[Bugs-r-devel] Some Progress

[Rodney S. <rsp...@mc...>]

Hi Guys:

Unfortunately, the patch did not fix the problem.  But, maybe it helped
since now I'm getting an error message that I didn't have before:

fixme:shell:StrRetToStrNW unknown type!

Looking at the Wine sources, this function is on line 83 of 
dlls/shell32/shellstring.c

This is one of the undocumented functions so I'm not clear
and exactly it's purpose.  Based on the type of src, do something?
However, the type of src is not one of the 3 types handled and 
nothing is returned!  

Looking at the value of tempdir() gave me an idea why that might be:

> tempdir()
[1] "/var/folders/z4/z4O5IqhPED0pjZUVP7s0mE+++TI/-Tmp-//RtmphdzhHo"

There appears to be an R bug here.  Two slashes in a row is not
what is wanted.  Of course, on Unix, this makes no difference since
the extra slash is ignored.   But, we are not dealing with Unix, we
are dealing with Wine's implementation of the Windows API.  So, after
setting working.directory=tempdir() can we substitute single slashes
for double slashes in working.directory

so that we get the following instead:

"/var/folders/z4/z4O5IqhPED0pjZUVP7s0mE+++TI/-Tmp-/RtmphdzhHo"

I spent some time looking through my S manual trying to find the
function to do this, but I couldn't figure it out.  Do S and R
support AWK functions since they were both invented at Bell Labs
(if memory serves)?
